Challenges of Treating a C2 Odontoid Fracture in an Elderly Patient With Multiple Comorbidities: A Case Report.

An 88-year-old male with a history of cervical spondylosis (status post laminectomy of C2-C3 and laminoplasty of C4-C5), chronic congestive heart failure (CHF), pulmonary embolism, and lumbar spinal stenosis presented to an outpatient sports medicine clinic with neck pain following a fall five days prior due to loss of balance. He reported pain on the left side worsened by movement and accompanied by neck "clicking." A physical exam showed severe limitation in cervical spine extension limited by pain and loss of lordotic curve and a neurologic exam demonstrated weakness in the left leg secondary to a previous back surgery.

Identifying delay in glymphatic clearance of labeled protons post-acute head trauma utilizing 3D ASL MRI (arterial spin labeling): a pilot study.

This study correlated mild traumatic brain injury (mTBI) cognitive changes with ASL-MRI glymphatic clearance rates (GCRs) and recovery with GCR improvement. mTBI disrupts the blood brain barrier (BBB), reducing capillary mean transit time and GCRs. mTBI is clinically diagnosed utilizing history/examination findings with no physiologic biomarkers.
